Pooling groups of wireless communication users

ABSTRACT

Systems and methods for pooling a plurality of telecommunication users into groups is disclosed. One method includes ranking the telecommunication users in an order based on a usage parameter. The usage parameter, for example, may be the average service usage time per billing period. Once ranked, the telecommunication users are pooled into at least two groups, each group comprising at least one telecommunication user within a range of ranks. The method may further include calculating estimated costs for the users to use cost-effective rate plans selected from a group of available rate plans and re-pooling the users into other possible combinations to determine the most cost-effective pooling combination and respective rate plans.

CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation-in-part application of U.S. patent application Ser. No. 09/758,824, filed Jan. 11, 2001, and entitled “System and Method for Determining Optimal Wireless Communication Service Plan Based on Historical Projection Analysis,” which claims the benefit of U.S. Provisional Application No. 60/230,846, filed on Sep. 7, 2000, and entitled “System and Method for Analyzing Wireless Communications Records and for Determining Optimal Wireless Communication Service Plans,” both of which are incorporated by reference herein in their entirety.

FIELD OF THE INVENTION

The present invention is generally related to wireless telecommunication, and, more particularly, is related to a system and method for analyzing wireless communication data to enable the determination of an optimal wireless communication service plan.

BACKGROUND OF THE INVENTION

Because immediate access to information has become a necessity in virtually all fields of endeavor, including business, finance and science, communication system usage, particularly for wireless communication systems, is increasing at a substantial rate. Along with the growth in communication use has come a proliferation of wireless communication service providers. As a result, a variety of wireless communication service alternatives have become available to consumers and businesses alike.

Subscribers to communication services, particularly wireless communication services, and the businesses that may employ them, who are dissatisfied with the quality of service or the value of the service provided by a particular provider, may terminate their current service and subscribe to a different service. Unfortunately, due to the vast number of communication service providers available, it is difficult to determine an optimal service plan, as well as optional service packages. In addition, due to the competitive nature of the wireless communication field, the cost and options made available with service plans frequently change, adding to the difficulty of finding the most optimal service plan available at a specific time.

Thus, a heretofore unaddressed need exists in the industry to address the aforementioned deficiencies and inadequacies.

SUMMARY OF THE INVENTION

In light of the foregoing, the invention is a system and method for determining optimal wireless communication service plans.

Generally, describing the structure of the system, the system uses at least one transceiver that is configured to receive billing information associated with a subscriber of a telecommunications service under a current rate plan that is stored in a storage unit. A processor is also used by the system which is configured to: process the subscriber related billing information to produce organized data in a calling profile record for each telecommunication service being used by the subscriber; create a usage history table and a call detail table within the storage unit from the processed billing information; analyze the processed data in relation to at least one rate plan of at least one telecommunication service provider; determine at least one proposed rate plan that would save the subscriber telecommunication costs relative to the current rate plan, via use of the usage history table and call detail table; and, produce a report of the at least one proposed rate plan to enable selection of a best telecommunication service provider and a best rate plan.

The present invention can also be viewed as providing a method for analyzing wireless communication records and for determining optimal wireless communication service plans. In this regard, the method can be broadly summarized by the following steps: receiving billing information associated with a subscriber of a telecommunication service under a current rate plan; processing the subscriber related billing information to produce organized data in a calling profile record for each telecommunication service being used by the subscriber; creating a usage history table and a call detail table from the processed billing information; analyzing the processed data in relation to at least one rate plan of a plurality of at least one telecommunication service provider; determining at least one proposed rate plan that would save the subscriber telecommunication costs relative to the current rate plan, via use of the usage history table and call detail table; and producing a report of the at least one proposed rate plan to enable selection of a best telecommunication service provider and a best rate plan.

The invention has numerous advantages, a few of which are delineated hereafter as examples. Note that the embodiments of the invention, which are described herein, possess one or more, but not necessarily all, of the advantages set out hereafter.

One advantage of the invention is that it automatically provides a subscriber with the best telecommunication service provider and the best rate plan without necessitating unnecessary subscriber interaction.

Another advantage is that it improves the quality of service and the value of the telecommunication services received by a subscriber.

Additional systems and methods are described herein for pooling telecommunication users into groups. One such method, among other possible methods, comprises ranking a plurality of telecommunication users in an order based on a usage parameter. The usage parameter, for example, may be the average number of minutes of telecommunication service used by the user during one billing period. Once ranked, the users are pooled into at least two groups, wherein each group contains at least one user within a range of ranks based on the usage parameter.

Computer programs are also disclosed herein for pooling users, one such computer program comprising logic for pooling a plurality of users into at least two groups, each group comprising at least one user having a usage parameter within a defined range. The program also includes logic for determining the most cost-effective rate plans based on the pooling of the users. The determining logic may further optimize the pooling combination with respect to a plurality of available rate plans for reducing the telecommunication service costs.

Other systems, methods, features, and advantages of the present invention will be or become apparent to one with skill in the art upon examination of the following drawings and detailed description. It is intended that all such additional systems, methods, features, and advantages be included within this description, be within the scope of the present invention, and be protected by the accompanying claims.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

The moving average monthly bill analysis (MAMBA) system 100, as is structurally depicted in FIGS. 1, 2A, and 2B can be implemented in software, hardware, or a combination thereof. In the preferred embodiment, as illustrated by way of example in FIG. 2A, the MAMBA system 100, along with its associated methodology, is implemented in software or firmware, stored in computer memory of the computer system, and executed by a suitable execution system. If implemented in hardware, as in an alternative embodiment, the MAMBA system 100 can be implemented with any or a combination of the following technologies, which are well known in the art: a discrete logic circuit(s) having logic gates for implementing logic functions upon data signals, an application-specific integrated circuit (ASIC) having appropriate combinational logic gate(s), programmable gate array(s) (PGA), field programmable gate array(s) (FPGA), etc.

Note that the MAMBA system 100, when implemented in software, can be stored and transported on any computer-readable medium for use by or in connection with an instruction execution system, apparatus, or device, such as a computer-based system, processor-containing system, or other system that can fetch the instructions from the instruction execution system, apparatus, or device and execute the instructions. In the context of this document, a “computer-readable medium” can be any means that can contain, store, communicate, propagate, or transport the program for use by or in connection with the instruction execution system, apparatus, or device. The computer-readable medium can be, for example but not limited to, an electronic, magnetic, optical, electromagnetic, infrared, or semiconductor system, apparatus, device, or propagation medium. More specific examples (a nonexhaustive list) of the computer-readable medium would include the following: an electrical connection (electronic) having one or more wires, a portable computer diskette (magnetic), a random access memory (RAM) (magnetic), a read-only memory (ROM) (magnetic), an erasable programmable read-only memory (EPROM or Flash memory) (magnetic), an optical fiber (optical), and a portable compact disc read-only memory (CDROM) (optical). Note that the computer-readable medium could even be paper or another suitable medium upon which the program is printed, as the program can be electronically captured, via for instance optical scanning of the paper or other medium, then compiled, interpreted or otherwise processed in a suitable manner if necessary, and then stored in a computer memory. As an example, the MAMBA system 100 software may be magnetically stored and transported on a conventional portable computer diskette.

By way of example and illustration, FIG. 1 illustrates a typical Internet based system upon which the MAMBA system 100 of the present invention may be implemented. It should be noted that while the present disclosure provides implementation of the MAMBA system 100 within an Internet based system, the MAMBA system 100 need not be provided via use of the Internet. Instead, one of reasonable skill in the art will appreciate that the MAMBA system 100 may be implemented within other mediums, such as, for example, but not limited to, a local area network (LAN), or wide area network (WAN).

Alternatively, instead of implementing the MAMBA system 100 via use of the Internet, the MAMBA system 100 may also be implemented via use of a first transmitting and receiving device such as, but not limited to, a modem located at a customer premises, which is in communication with a second transmitting and receiving device such as, but not limited to, a modem located at a central office. In accordance with such an embodiment, personal computers may be located at the customer premises and the central office having logic provided therein to perform functions in accordance with the MAMBA system 100.

Referring to FIG. 1, a plurality of networks 21A, 21B are shown wherein each network 21 includes multiple digital processors 33, 35, 37. Digital processors 33, 35, 37 within each network 21 may include, but are not limited to, personal computers, mini computers, laptops, and the like. Each digital processor 33, 35, 37 is typically coupled to a host processor or server 31 a, 31 b for communication among processors 33, 35, 37 within the specific corresponding network 21.

The host processor, or server, 31 is coupled to a communication line 41 that interconnects or links the networks 21A, 21B to each other, thereby forming an Internet. As such, each of the networks 21A, 21B are coupled along the communication line 41 to enable access from a digital processor 33 a, 35 a, 37 a of one network 21A to a digital processor 33 b, 35 b, 37 b of another network 21B.

A client server 51 is linked to the communication line 41, thus providing a client with access to the Internet via a client digital processor 53, as further described hereinbelow. In accordance with the preferred embodiment of the invention, the software for implementation of the MAMBA system 100 is provided by a software program that is operated and located on an analyzing digital processor 71, and connected through an analyzing server 61, to the communication line 41 for communication among the various networks 21A, 21B and/or digital processors 33, 35, 37 and the client connected to the Internet via the client server 51.

It should be noted that the number of client servers, client digital processors, analyzing digital processors, and analyzing servers may differ in accordance with the number of clients provided for by the present MAMBA system 100. As an example, if five separately located clients were utilizing the MAMBA system 100, five separate client digital processors may be connected to a single client server, or five separate client servers.

In accordance with the preferred embodiment of the invention, the client digital processor 53 may be any device, such as, but not limited to, a personal computer, laptop, workstation, or mainframe computer. Further, the networks used by the MAMBA system 100 are preferably secure and encrypted for purposes of ensuring the confidentiality of information transmitted within and between the networks 21A, 21B.

The analyzing digital processor 71, further depicted in FIG. 2A, is designed to analyze the wireless communication data, received either from the wireless communication provider, the client, or a third party in order to determine the optimal wireless communication service plans. As shown by FIG. 2A, the analyzing digital processor 71 includes logic to implement the functions of the MAMBA system 100, hereinafter referred to as the MAMBA software 10, that determines the optimal service plan stored within a computer memory 73.

Several embodiments of the analyzing digital processor 71 are possible. The preferred embodiment of analyzing digital processor 71 of FIG. 2A includes one or more central processing units (CPUs) 75 that communicate with, and drive, other elements within the analyzing digital processor 71 via a local interface 77, which can include one or more buses. A local database 74 may be located within the analyzing digital processor 71. It should be noted that the database 74 may also be located remote from the analyzing digital processor 71. Furthermore, one or more input devices 79, for example, but not limited to, a keyboard or a mouse, can be used to input data from a user of the analyzing digital processor 71. One or more output devices 81, for example, but not limited to, a screen display or a printer, can be used to output data to the user. A network interface 83 can be connected to the Internet to transfer data to and from the analyzing digital processor 71.

Referring to FIG. 2B, the client digital processor 53 of FIG. 1 is further illustrated. Several embodiments of client digital processor 53 are possible. In accordance with the preferred embodiment of the invention, the client digital processor 53 includes one or more CPUs 57 that communicate with, and drive, other elements within the client digital processor 53 via a local interface 59, which can include one or more buses. A local database 56 may be located within the client digital processor 53. It should be noted that the database 56 may also be located remote from the client digital processor 53. The client digital processor 53 also includes a memory 55 that houses software to provide a browser 16. Furthermore, one or more input devices 62, for example, a keyboard or a mouse, can be used to input data from a user of the client digital processor 53. One or more output devices 63, for example, but not limited to, a screen display or a printer, can be used to output data to the user. A network interface 65 can be connected to the Internet to transfer data to and from the client digital processor 53.

FIG. 3 is a flowchart that illustrates logical steps taken by the MAMBA system 100. Any process descriptions or blocks in flow charts illustrated or described in this document should be understood as representing modules, segments, or portions of code which include one or more executable instructions for implementing specific logical functions or steps in the process, and alternate implementations are included within the scope of the preferred embodiment of the present invention in which functions may be executed out of order from that shown or discussed, including substantially concurrently or in reverse order, depending on the functionality involved, as would be understood by those reasonably skilled in the art of the present invention.

As shown by block 120, data regarding a given cellular account, subscriber, or group of subscribers if the service is provided for a corporate customer, is provided by a carrier. As shown by block 130, the data is loaded into the analyzing digital processor database 74 by a dataloader process 320 (shown in FIG. 5 below). The loaded data is then analyzed. Analysis of the loaded data includes, but is not limited to, the steps of: creating a calling profile (block 140) for each billing period by running a buildProfile process (explained in detail below, with reference to FIG. 5); identifying optimal service plan options for each profile period (block 150); and making recommendations as to the best service plan and options (block 160), wherein service plan options are across multiple profile periods, by running a decideplan process (FIG. 5400). The results are then rendered to a user (block 170). In accordance with the preferred embodiment of the invention, the MAMBA system 100 then repeats the logical steps beginning with block 130 in accordance with a predefined periodic basis (block 180). The logical steps taken by the MAMBA system 100 are further explained hereinbelow.

The MAMBA system 100 can be offered on an application service provider (ASP) basis to telecommunication personnel at the customer premises, or to purchasing or other appropriate managers or administrators of wireless services at corporations, government agencies and/or similar organizations as a “cost assurance” tool. The MAMBA system 100 assures that all of the wireless accounts or subscribers under the management or control of administrators are on the best possible service plan, given their specific usage profile trends, and therefore minimizes overall expenditures for wireless services by the enterprise.

The MAMBA system 100 is an extension of the existing “one user at a time” Hypertext Markup Language (HTML)-based profiler application, which takes as input from an individual account or subscriber, via an HTML or Web-based interface, an interactively constructed user-defined profile, i.e., how many minutes of airtime a user may consume according to the three “W's” that, combined, bound the mobile calling environment: “When” (peak, off-peak, or weekend), “What” (local or toll), and from “Where” (home market or non-home market) the call is made. This calling profile, entered via the profiler HTML page, is then provided as input to an analysis component labeled an “optimator,” which provides as output the best set of possible service plans, including optional packages, promotions, etc., based upon the entered calling profile. The results are presented to the user in the same HTML/Web-based format.

Several embodiments of a profiler application 200 are possible. By way of example, the flow of logic comprising one possible embodiment of the profiler application 200 is shown in FIG. 4. The logic is represented in flow charts that interrelate. In the profiler application 200 of FIG. 4, an inc_plan_loading.asp function 205 collects a user's usage profile information via a user interface, such as, but not limited to, an HTML-based input page/screen. The usage profile preferably comprises the following: the expected quantity of wireless usage to be utilized during a given billing period (usually, but not exclusively, a one month period); how the expected usage will be distributed according to time-of-day and day-of-week; how the usage was expected to be distributed by local versus toll calling; and the expected distribution according to the location where calls are made or received. A dbAccount putProfile function 215, which is connected to a bus_Account putProfile function 210, then writes this profile information to the analysis digital processor database 74.

The bus_Account putProfile function 210 is connected to an optimator doEval function 250 and to service plan (SP) instances 260, 270 via the inc_plan_loading.asp function 205, which presents the usage profile information stored via the dbAccount putProfile function 215 to the optimator doEval function 250.

The optimator doEval function 250 then presents a list of user-provided ZIP codes, symbolic of where the user can purchase service (at least their home zip code and possibly one or more zip codes of locations for the user's place of employment) from the user profile, to an optimator findPackages function 225. The optimator findPackages function 225 is, in turn, connected to an SPPackage getPackagesByZIP function 220 which determines which wireless service plan packages are offered within the user provided ZIP codes. The SPPackage getPackagesByZIP function 220 then presents these wireless service plan packages to the optimator doEval function 250 via the optimator findPackages function 225. The optimator doEval function 250, in turn, presents the plan packages and the user profile information to an optimator calcCosts function 235 which then calls an SPPackage calcCost function 230 to calculate and organize, from lowest cost to highest cost, the cost of each service plan package combination for the given user usage profile. The cost information is then presented to the optimator doEval function 250 which uses an optimator createEvaluation function 245 and a dbOptimator putEvaluation function 240 to write the resulting evaluations, which represent comparison of the user usage profile to available service plans, to a database.

Finally, the optimator doEval function 250 utilizes a combination of an SPInstance getEvalID function 255, an SPInstance getEval function 260, a dblnstance getSPInstance function 265 and an SPInstance getSPInstance function 270 to present the results to the user via the inc_plan_loading.asp function 205.

The MAMBA system 100 extends the ad hoc profiler application 200 into a multi-account or subscriber-automated and recurring process that provides an analysis of periodically loaded wireless service usage of a given account or subscriber, and/or group of accounts or subscribers (e.g., a set of subscribers all employed by the same company and all subscribing to the same carrier), and determines whether or not that subscriber, or group of subscribers, is on the optimal wireless service plan according to the particular subscriber's usage patterns across a variable number of service billing periods. If not, the MAMBA system 100 suggests alternative cellular service plans that better meet the users' usage patterns and that reduce the overall cost of service to the account/subscriber.

FIG. 5 represents the functional “flow” among the major MAMBA system 100 components and their read from/write to interaction with the most significant data tables that are most directly utilized or affected by the analysis. Functionally, the MAMBA system 100 is comprised of the following five (5) processes, which further elaborate upon the flow chart of FIG. 3:

-   1) Using the Data Loader (DL) process 320, call detail records are     imported from either the subscriber or the carrier information     sources 310, either in the form of CDs and/or diskettes provided by     an end user or via direct connection with carriers through file     transfer protocol (FTP) or other communication means, into     usage_history table 330 and call_detail table 340. While this step     is actually not a part of the MAMBA system 100 per se, as the DL     process 320 application may serve the analysis service offered, it     may be a prerequisite process that should be modified in order to     support the MAMBA system 100. Depending upon the final     implementation strategy for the DL process 320, a staging table may     be utilized as a subset of the total data set potentially provided     by each carrier as may be used by the MAMBA system 100. Such a     staging table would allow for a minimum set of data used to populate     the call_detail table 340 to be extracted. It should be noted that     the DL process 320 is further defined with reference to FIGS. 6 and     7 hereinbelow. -   2) In accordance with the second process, the buildProfile process     350 of FIG. 5 is created from the imported call detail tables 340.     The MAMBA system 100 uses the call detail table 340 for a given     billing period to create a calling profile record within a calling     profile table 360, for each account of a given client. The calling     profile record represents in a single data record the wireless     service usage for the client's account, which for a single     subscriber and in a single billing period could represent the sum     total of the information captured by hundreds or thousands of     individual calls as recorded by the wireless service provider in the     form of call detail records (CDRs).

The calling profile record provides a subscriber's CDRs according to the following three parameters: “when calls are made/received”, according to time-of-day and day-of-week; “what kind of calls are made or received”, either local or toll; and, “where calls are made or received” which is categorized into home, corporate and/or a variable number of alternate zip codes. With reference to the “where” parameter, if the number of alternate zip codes exceeds the number available for the calling profile record, then an additional algorithm is used to map the alternate zip codes in excess of those allowed by the calling profile data record into one of the allowed alternate zip codes “buckets”. As an example, for four alternate markets, the MAMBA system 100 uses additional “bucketizing” logic to map any “where” usage information that goes beyond the four (4) alternate market buckets onto one of the four (4) markets. It should be noted that bucketizing is further defined with reference to FIG. 8 hereinbelow.

-   3) In accordance with the third process, namely the optimator     process 370, the calling profile records 360 are used by the     optimator process 370, as is further described hereinbelow. The     optimator process 370 evaluates the calling profile records 360 to     determine whether or not the client's current calling plan is the     most cost effective for the usage represented by the calling profile     360 under analysis and recommends a variable number of     cost-effective calling plans. This recommendation may take the form     of a rate plan evaluation record in a service plan (SP) instance     table 380 and at least one linked service plan instance record 390.     It should be noted that the optimator process 370 is further defined     with reference to FIG. 9 hereinbelow. -   4) The fourth process, namely the decide plan process, uses the     decideplan process 400 to compare the results from the optimator     process 370 to the cost, based upon usage history, for the current     service plan an account, or client subscriber, is using. The     decidePlan process 400 then selects the best possible plan using a     “historical predictor” algorithm and several related statistical     filters that, together, make a decision engine. It should be noted     that the decideplan process 400 is further defined with reference to     FIG. 12 hereinbelow. -   5) In a fifth process, namely the presentResults process 410, the     MAMBA system 100 renders the recommendations from the optimator     process 370 to the client and executes any actions the client wants     to take as a result of those recommendations. As such, the MAMBA     system 100 gathers information at different points during its     processing and stores that information for use in presentation to     the client in a rendition of the results 410. It should be noted     that the present results process is further described hereinbelow     under the title “Presentation of Recommendations or Actions.”     dataLoader (DL)

FIG. 6 further illustrates the DL architecture and process 320. The DL process 320 is used to import data from external data sources, such as, for example, CD-ROMs or other storing mediums, such as diskettes provided by customers, or through direct data feeds from carriers serving those customers, to populate the database 420, preferably a Microsoft-structured query language™ (MS-SQL™) database, which is manufactured by, and made commonly available from Microsoft Corporation, U.S.A., with the call detail and usage history information used by the MAMBA system 100. Other suitable database packages may be used, of which MS-SQL™ is merely an example. Preferably, the DL process 320, the results of which also support the Analysis ASP offering in addition to the MAMBA system 100, makes use of a set of ActiveX components to load requisite data from the provided sources. These components may, for instance, support the import of data from Microsoft Access™, Dbase IV™, Microsoft Excel™ and Microsoft SQL™ databases 430. It should be noted that other databases may be used in accordance with the present invention.

The DL process 320 makes use of two text files, namely, a “Map” file 440 and a “Visual Basic, Scripting Edition (VBS)™” file 450, to flexibly define or control the configuration of the data import process. The “Map” file 440 dictates to the DL process 320 how to map incoming data fields to destination data fields. The “VBS” file 450 is used by the DL process 320 to perform any custom transformations of input data before writing it to a destination, e.g., get dow_id from day_of week. The Map 440 and VBS files 450 are developed as part of the data conversion process undertaken whenever new input data formats are presented by a customer base or carrier relationship base.

The DL process 320 is used to import initial customer data as well as to import ongoing call detail data. In one implementation of the invention, each of these data loads has a “base” set of user-provided data existing in a destination database, such as, for example, the local database 74 located within the analyzing digital processor 71 of FIG. 2A, and then loads new data into the database. In accordance with the preferred embodiment of the invention, data shown in Table 1 hereinbelow exists in the database prior to execution of the DL process 320. It should be noted that the following is by no means a conclusive list of data and, as such, other data may exist within the database, or less data may exist within the database. TABLE 1 Data Tables that Exists in Database Prior to Running the DL Process ACCESSORY_ITEMS ACCESSORY_PRODUCT_LINK ACTIVITY ACTIVITY_LINK ADDRESS ADDRESS_TYPE BTA CARRIER CARRIER_ADDRESS_LINK CARRIER_CONTACT_LINK CARRIER_DBA CONTACT CONTACT_TYPE COUNTY COVERAGE_AREA_BTA_LINK COVERAGE_AREA_MRSA_LINK DB_HISTORY FCC_CELL_LICENSE FCC_PCS_LICENSE LERG_FOREIGN LERG_US MRSA MTA MTA_MRSA_LINK NATION PHONE_ITEMS PHONE_PRODUCT_LINK PRODUCT_BUNDLE_ITEMS PRODUCT_FAMILY PRODUCT_INFO_STATUS_TYPE REQUEST_STATUS REQUEST_TYPE SERVICE_PLAN SERVICE_PLAN_STATUS_TYPE SP_FEATURE SP_FEATURE_BUNDLE SP_FEATURE_BUNDLE_LINK SP_FEATURE_TYPE SP_PACKAGE SP_PACKAGE_COVERAGE_LINK SP_PACKAGE_TYPE SP_PHONE_ITEM_LINK SP_TAX STATE STATE_MTA_LINK TECHNOLOGY_TYPE USERINFO_STATUS_TYPE ZIP_CODE

The initial customer data load may then be loaded within the tables shown in Table 2. TABLE 2 Data Tables into which Customers Initially Load Data ACCOUNT ACCOUNT_ADDRESS_(—) ADDRESS LINK ADDRESS CLIENT CLIENT_ADDRESS_(—) LINK DEPARTMENT PHONE_ITEMS REQUEST_LOOKUP TELEPHONE USAGE_HISTORY USER

In accordance with one embodiment of the DL process 320, in the ongoing call detail data load the initial customer load may be completed prior to the running of the DL process 320. The ongoing call detail load may load data into the following tables shown in Table 3. TABLE 3 Data Tables into which Customers May Load Ongoing Call Detail CALL_DETAIL PACKAGE_INSTANCE SERVICE_PLAN SERVICE_PLAN_(—) SP_PACKAGE INSTANCE

The call_detail table shown in Table 3 contains the minimum set of information provided by the wireless providers detailing calls made which can be reduced into a single calling_profile by the buildprofile process 350. The layout of the call_detail table is shown in Table 4. TABLE 4 Layout of Call_detail Table Field Name Data Type Call_detail_id Integer Usage_id Integer billing_period Datetime mkt_cycle_end Datetime invoice_number Varchar billing_telephone_number Varchar originating_date Datetime originating_time Varchar originating_city Varchar originating_state Varchar terminating_number Varchar call_duration Decimal air_charge Money land_charge Money Surcharge Money Total Money user_last_updt Varchar tmsp_last_updt Datetime dow_id Integer

It should be noted that the dow_id field, as well as other fields, may contain a numerical representation of data to be inputted within a field, such as, instead of text for the day of the week that a call was placed, using 1=Sunday, 2=Monday, etc.

Operation of DataLoader Process

FIG. 7 is a logical diagram that depicts operation of the DL process 320. As shown by block 321, the DL process 320 application can be started manually or as a result of a trigger event such as the posting of a customer's monthly data on an FTP site, or some similar type of event. As shown by block 322, initial user data is then selected. The DL script process is then run, as shown by block 323.

In accordance with the preferred embodiment of the invention, the DL script process includes the following steps. As shown by block 324, the DL script process is first started. Parameters are then retrieved from the dataloader process 320 application, as shown by block 325. As shown by block 326, the user's authorization is then checked in order to run the dataloader process 320 application. As shown by block 327, all pre-process SQL scripts are then executed to check the integrity/validity of the data and to otherwise put the data into the appropriate format for data transformation. Data transformation services (DTS) 328 are then used to load the pre-processed data. As shown by block 329, all post-process SQL scripts are then executed to confirm the integrity/validity of the data, after which the DL script is exited (block 331).

After the DL script process 323 is run, the DL process 320 selects a wireless service provider, or carrier, provided customer account and related (e.g., usage history) data 332. The DL script process is then run again 333, after which the DL process 320 selects “CallDetail Data” 334. As shown by block 335, the DL script process once again runs, after which the DL application ends block 336.

Build Profile Process

The following further illustrates the build profile process 350 with reference to FIG. 5, in accordance with the preferred embodiment of the invention. FIG. 5 depicts input and output of the optimator 370. The MAMBA system 100 provides a method to create calling_profile records 360 from the call_detail data 340 imported using the DL process 320. These calling_profile records 360 provide a rolled-up view of each account's call usage, reducing for a given account or subscriber what may be, for example, the hundreds or thousands of individual call detail records (N) generated into a single calling_profile record 360. This data reduction reduces the computations performed by optimator 370 in order to analyze a single account or subscriber by a similar amount.

The calling_profile record 360 is created by the build Profile process 350. This record is used by the optimator process 370, which provides a service plan comparison and generates a list of potential service plans that may better fit the account or subscriber's particular calling profile. The calling_profile record 360 contains the fields and source data shown in Table 5. TABLE 5 Fields and Source Data Contained in calling_profile Record Field Name Data Type Len Source data profile_id Integer IDENTITY field account_id Integer from the user/account record date_created DateTime current date billing_period DateTime contains the billing period periods_averaged Integer contains the number of periods averaged for this record. monthly_minutes Integer sum of all minutes for a month peak_percentage Decimal buildProfile process offpeak_percentage Decimal buildProfile process local_percentage Decimal buildProfile process home_zip Varchar 20 From the user/address record corp_zip Varchar 20 From the user/client/ address record alt_zip1 Varchar 20 buildProfile process alt_zip2 Varchar 20 buildProfile process alt_zip3 Varchar 20 buildProfile process alt_zip4 Varchar 20 buildProfile process home_zip_percentage Decimal buildProfile process corp_zip_percentage Decimal buildProfile process alt_zip1_percentage Decimal buildProfile process alt_zip2_percentage Decimal buildProfile process alt_zip3_percentage Decimal buildProfile process alt_zip4_percentage Decimal buildProfile process total_calls Integer buildProfile process total_rejected_calls Integer buildProfile process user_last_updt Varchar 20 Username of person creating record tmsp_last_updt DateTime Current date

The originating_city and originating_state from each call_detail record 340 may be used to determine the originating postal_code from the zip_code table. This process results in some degree of approximation because of the different methods employed by the carriers to input the destination_city information, e.g., Kansas_cit for Kansas City. However, using both the originating_city and originating_state minimizes the chances of selecting the wrong city, e.g., avoiding selecting Austin, Pa. instead of Austin, Tex., because of including the originating_state in this process.

All calls not made from either the home or corporate zip code are separated by originating_city, originating_state zip code and the total number of minutes added for each. Once calls have been separated into separate zip codes, using one implementation of the buildProfile process 350, if there are four or fewer zip codes, the zip codes may be written to the zip code fields, e.g., alt_zip1, alt_zip2, alt_zip3 and alt_zip4, in descending order by the amount of minutes for each zip code and the corresponding minutes, as a percentage of the total, may be written to the corresponding zip code percentage fields, e.g., alt_zip1_percentage, alt_zip2_percentage, alt_zip3 percentage and alt_zip4_percentage.

However, in this particular implementation, if there are more than four zip code sets, the zip code with the highest number of minutes is written to alt_zip 1. Then the remaining zip codes are grouped by combining zip codes with the same first 3 digits, e.g., 787xx, and adding up the associated minutes.

Once this grouping has been completed, and if there are more than three groupings in this implementation, the zip code from the grouping with the highest number of minutes is added to alt_zip2. The remaining zip codes may then be grouped by combining zip codes with the same first two digits, e.g., 78xxx, and adding up the associated minutes.

Once this grouping has been completed, and if there are more than two groupings in this implementation, the zip code from the grouping with the highest number of minutes is added to alt_zip3. The remaining zip codes may then be grouped by combining zip codes with the same first digit, e.g., 7xxxx, and adding up the associated minutes. Once this grouping has been completed, the zip code with the highest number of minutes may be added to alt_zip4.

Once completed, the percentages may be computed from the total number of minutes and written to each zip code percentage field, including the home_zip_percentage and corp_zip_percentage fields. The periods_averaged field of the build Profile process 350 contains the number of periods averaged to create this record. Records that are created by the buildProfile process 350 contain a value of 1 in this field. Records created by the “AvgProfilesByClient” or the “AvgProfilesByAccount” functions contain the number of profile records found for the given client or account with a billing period during the given dates. However, this value may be decremented due to the fact that the user has changed home market during that time frame.

Operation of BuildProfile Process

FIG. 8 depicts the operation of a buildprofile process 350. As shown by block 351, a mambaLaunch application is started either manually or based upon a trigger event such as those mentioned above. As shown by block 352, the buildProfile process 350 calls a “TwiMamba.clsMamba.Build Profiles” function. As shown by block 353, the buildProfile process 350 is then started. As shown by block 354, the process gets “callDetail” records for the accounts for the given client and date range. As shown by block 355, the process analyzes the calls and, as shown in block 356, creates the profiles record. As shown by block 357, the program then exits the buildprofile process 350. The process then returns to the mambaLaunch application and, as shown by block 358, executes a function write profile identifications to file. As shown by block 359, the buildprofile process 350 then exits mambaLaunch Application.

Data “Bucketizing” Functions

The data “bucketizing” functions, previously mentioned with reference to the buildProfile process 350 portion of FIG. 5, guide the analyzing and classifying of the call detail data 340 for use in the MAMBA system 100 processes. These functions provide the data classification and reduction used to populate the calling_Profile record 360 of the MAMBA system 100. This structure is organized according to three dimensions or parameters of a call, and are as follows:

-   1) “When”: time of day (ToD) and day of week (DoW). “When”     parameters are used to determine when a call was made or received as     determined by three (3) “buckets”:     -   peak, off peak or weekend. The service plan record of the         service plan that a subscriber is currently using functions as         the default ToD and DoW parameters.         The ToD/DoW parameters are as follows:

For the subscriber under consideration, if the call_date, dow_id (1-7 with each number corresponding to a fixed day of the week) is not between the weekend_start_dow and the weekend_end_dow, and was placed between weekday_peak_start and weekday_peak_end times, then the call is characterized as a “peak call.”

For the subscriber under consideration, if the call_date, dow_id is not between the weekend_start_dow and the weekend_end_dow, and was not placed between weekday_peak_start and weekday_peak_end times, then the call is considered an “off-peak call.”

If the call_date, dow_id equals the weekend_start_dow and was made after the weekday_peak_end time or if the call_date, dow_id is on the weekend_end_dow and was made before the weekday_peak_start time, or if the call_date, dow_id falls between the weekend_start_dow and the weekend_end_dow, then the call is considered a “weekend call.”

-   2) “What”: Type of Call—local or toll. These parameters determine     the type of call that was made/received as determined by three (3)     “buckets”: local, intrastate_toll and interstate_toll.     The local/toll parameters are as follows:

If called_city equals “incoming” or <null> or called_number equals <null> then the call is a “local call.”

If the mobile_id_number lata_number (as derived from npa-nxx number combination)=destination_number lata_number, as derived from the npa-nxx number combination, then the call is considered to have been originated and terminated within the same Local Access Transport Area (LATA) and is therefore categorized as a “local call.” As known by those skilled in the art, a npa-nxx is defined as the numbering plan area (NPA) and office code (Nxx) of an end user's telephone number.

If neither of the two parameters above is true, then the call is a “toll call.”

If the mobile_id_number lata_number state (as derived from the npa-nxx number combination)=destination_number lata_number state, as derived from the npa-nxx number combination, then the call is considered to have originated and terminated within the same sate and is therefore categorized as an “intrastate_toll call.”

If none of the above parameters are applicable, then the call is an “interstate_toll call.”

These tests may use a table that allows a local access transport area (LATA) number to be associated with an npa_nxx. The LATA (npa_xxx) information also contains city and state information. A Local Exchange Routing Guide (LERG) table may also contain the information used.

-   3) “Where”: Where calls are made or received (home or non-home).     These parameters determine where calls were made or received by the     mobile end of the wireless communications connection represented by     the call detail record under consideration. Several possible buckets     may be defined according to different embodiments of the invention.     By way of example, under one embodiment of a set of data     “bucketizing” parameters, there may be the following six (6)     possible buckets defined: home_zip, corp_zip, alt1_zip, alt2_zip,     alt3_zip, alt4_zip.     The Home/non-Home parameters are as follows:

If the originating_city equals <null> or the lata_number of the originating_city, originating_state pair=the lata_number of mobile_id_number (npa_nxx matching), then the call was made from the “Home” region and allocated to the home_zip_percentage. Otherwise, the call is allocated to either the corporate_zip_percentage or one of the alt_zip_percentage “buckets, depending upon the zip code associated with the the originating_city and according to the alt_zip_percentage rules previously defined.

The Optimator Process

FIG. 9 depicts the optimator process 370, and how it is implemented. The optimator process 370 uses the calling_profile record 360 for a given subscriber as input for the analysis of the usage patterns to provide recommendations for the most economical cellular service plans (see FIG. 7) for the specific billing period associated with that profile record. Further, the optimator process 370 receives as input the various service_plans 720, service_plan (sp) packages 730, and coverage_areas 740 that are offered by various carriers and that are associated with each sp_package 730. The optimator process 370 may return different numbers of recommendations per analysis. For example, in one implementation, the optimator process 370 returns up to three recommendations per analysis. The number of recommendations can be changed through an “instance variable.”

The recommendations are created as records in the service_plan_instance 390 and package_instance tables 710. These records are linked to the associated account by a record in the rate_plan_evaluation table 380 which, in turn, is associated with the specific billing period associated with the calling_profile record. The optimator process 370 returns the identification of this new record.

Operation for Creating Rate Plan Evaluations

FIG. 10 depicts the operation for the process of creating rate plan evaluations 440. Block 351 depicts the step of starting the MAMBALaunch Application. As shown by block 381, a “TwiMAMBA.clsMAMBA.Run Profiler” process is called. As shown by block 382, a “runprofiler” process is started. As shown by block 383, the profile identification files created in block 358 of FIG. 8 are then read. As shown by block 384, a program “TwiOptimzer.Optimator.DoEval” is called. As shown by block 385, a “doEval” process is started. As shown by block 386, the current calling profile is read. As shown by block 387, the profile for the lower cost calling plans are then evaluated. As shown by block 388, the rate_plan_evaluation 380, service plan 390 and package instance 710 records are created. As shown by block 389, the doEval process is then exited. As shown by block 391, the runProfiler process makes the decision as to whether all profile identifications have been evaluated. If the answer is “no”, the program returns to block 384, in which TwiOptimzer.Optimator.DoEval function is again called and the program continues through each step again until block 391 is reached again. If the answer is “yes” in block 391, the runProfiler process is exited, as shown in block 392. The MAMBAlaunch application then writes the eval identifications (Ids) to the file, as shown in block 393. Then as shown by block 394, the MAMBAlaunch application is exited.

Averaging Profiles

FIG. 11 depicts the process of averaging profiles 810 and how it is implemented. The MAMBA system 100 allows the user to obtain a moving average 820 of the calling totals assigned to any calling profile records 360 that have a billing date within a given date range. This average 820 provides the user with a snapshot of cellular service use within a given period.

AvgProfilesByClient and avgProfilesByAccount (see “The MAMBA Component”) methods (FIGS. 39 and 40) allow the user to average the calling profiles by either client or individual account. These methods create a calling profile record 820 that contains the average of usage for the calling profiles 360 created during the given period, and then return the identification of the new record.

The decidePlan Process

Returning to FIG. 5, the optimator process 370 output, specifically a variable number of service_plan_instances 390, reflects the lowest cost options based upon the calling profile analyzed. As such, the optimator 370 results represent a single point-in-time period, for example, one month, for that particular user without taking into account any historical trending information that might be available for that user. What is therefore needed but has been heretofore unaddressed in the art, is a methodology for using a series of single period optimator 370 results 390 to determine the optimal service plan for that user over an appropriate period of time, as depicted in FIG. 5. The decidePlan process 400 leverages available chronological information to assist in the determination of what service plan would be optimal for a given wireless user.

The decideplan process 400 is based upon what can best be described as a “historical prediction” algorithm. Given the fundamental complexity of determining the optimal service plan solution set, the application of a traditional trend-based predictive methodology, e.g., a linear or other form of extrapolation, is not practical. Rather, the decidePlan process 400 leverages the “hindsight” intrinsic to a series of historical single period optimator 370 analyses in order to predict the optimal solution looking forward.

The decidePlan process 400 takes advantage of the “reactive system” type of behavior that is inherent in the analysis or decision process for selecting the optimal plan for a given subscriber. Specifically, the decision engine 400 calculates the total cost for a given set of optimator 370 generated service_plan_instances 390 over a known set of historical periods. The decidePlan process 400 then compares this total cost to the optimator 370 results of the corresponding service_plan_instances 390 for the most recent single period available, and on that basis predicts the optimal service plan going forward.

The known set of historical optimator 370 results is referred to herein as the “training set,” while the single most recent set of period results is referred to as the “test set”, where the test set period can also be included as part of the training set. An optimal service plan solution is selected from the training set and then compared to the result of the test set to determine how well the training set would have predicted the test set result. In implementing the training and test set, the data set to execute the historical prediction analysis is preferably a minimum of two periods, two periods for the training set and one period for the test set, in order to execute the historical prediction.

The relative attractiveness of a service plan instance 390 is determined by comparing it to the corresponding actual billed usage of the current service plan for the given period(s). The specific measure, termed “efficiency”, is calculated as the following ratio: efficiency=current plan costs/service plan instance estimated cost If the efficiency factor is greater than 1, then the service plan instance is more cost effective than the current plan. Among a group of service plan instances, the plan instance with the highest efficiency factor is the optimal solution.

Implementation of the historical prediction analytic and decision-making model is best demonstrated by way of example. Table 6 shows an exemplary two period set of optimator 370 results for a single subscriber. TABLE 6 Example of Historical Prediction Model for a Two Period Set of Results Training Efficiency Efficiency Set (Current/ Test Set (Current/ Month 1 Plan X) Month 2 Plan X) Calling 200 250 Profile MOUs PLANS A $50 1.38 $50 1.38 B $65 1.06 $65 1.06 C $40 1.73 $45* 1.53* D $60 1.15 $60 1.15 E $30* 2.30* $45 1.53* Current $69 1.00 $69 1.00 Where * indicates the lowest cost plan option Based upon this minimum two period data set, the training set predicts plan E as the optimal choice, a selection confirmed by the corresponding results for the test set (Month 2).

The larger the data set, where larger is measured by the number of periods of service plan instance results available for the training set, the better the forward looking “prediction” will likely be. Table 7 shows the same two period data set presented earlier in Table 6, extended by an additional four periods, for a total of six periods, with five applied to the training set and one to the test set. TABLE 7 Example of Historical Prediction Model for a Six Period Set of Results Training Set Training Sum Set Mon 6 Mon 1 Mon 2 Mon 3 Mon 4 Mon 5 1-5 efficiency Mon 6 Efficiency Calling 200 250 300 260 310 225 Profile MOUs PLANS A $50 $50 $60 $60 $62 $282 1.22 $50 1.38 B $65 $65 $65 $65 $65 $325 1.06 $65 1.06 C $40 $45 $50 $46 $52 $233* 1.48* $42 1.64 D $60 $60 $60 $60 $62 $302 1.14 $60 1.15 E $30 $45 $60 $48 $62 $245 1.41 $37* 1.86* Current $69 $69 $69 $69 $69 $345 1.00 $69 1.00 Where * indicates the lowest cost plan option In this case, use of only the most recent period's, month 6, optimator 370 output would have resulted in the selection of plan E as the optimal service plan option for this user or account. However, applying the historical prediction analysis, the total of 1-5 ranked by efficiency factor, the optimator 370 output indicates that plan C would be optimal choice for this user. Although plan E would have been the best option in for the most recent period, month 6, when the variability of this subscriber's usage profile is taken into account over the available six period data set, plan C would have been selected as the superior solution.

The above analysis assumes that the data in the test set has equal “value” in the analysis. In reality, the more recent the data set, or the “fresher” the data, the more relevant it is to the analysis as it reflects the more recent behavior of the user. Thus, the use of a weighting strategy which gives greater relevance to more current, fresher data as compared to the older, more stale data, improves the predictive results. Optionally, the weighing strategy can be added to the decideplan process if needed to provide such increase relevance to more recent data.

There are a number of possible weighting functions that can be applied. One possible weighting function would be an exponential envelope of the type: weighting factor=n+e ^((1-Period)) where n>=0 The weighting functions for n=0, n=0.5, n=1 and n=2 are plotted in FIG. 13. Data that is four periods old is weighted as 14% of that of the most recent month. The n=0 function more aggressively discounts older data than does the n=1 function, where the same four period back data is weighted at a level about one-half that of the most recent period data set.

Applying these two versions of exponential weighting envelopes to the previous six periods of training and test data sets generates the result set shown in Table 8, with the original “equal weighting” results shown as well for reference.

Although the result of the historical prediction analysis in this specific scenario does not change per se as a result of applying either weighting scheme to the training set, where both the n=1 and n=0 weightings identify Plan C as the optimal plan, the application of these two weighting envelopes do have the effect of increasing the “spread” between the efficiency factor of the optimal plan, plan C, as compared to the next best solution, plan E. This is compared against the actual cost because the weighting function that more heavily favors recent or fresher data, i.e., the n=0 exponential decay envelope, provides a greater efficiency spread (1.38-1.20, or 0.18) compared to the n=1 weighting function that less aggressively discounts older or more “stale” data (1.46-1.35 or 0.11).

The methodology, historical prediction with time-based weighting, described thus far does not take into account the intrinsic period-to-period variability in the user or account's behavior. One way this variability is reflected is by the user's usage of the account, as measured by the minutes of wireless service use on a period-by-period basis. By measuring the standard deviation in a usage set for the user or account, and comparing it to per period usage data, the suitability of the data set for each period can be assessed relative to the total available array of periodic data sets. In particular, a significant “discontinuity” in a usage pattern of a user or account, for example, as a result of an extraordinary but temporary amount of business travel, especially if such a spike occurs in a current or near-current data period, could skew the results of the analysis and provide a less-than-optimal service plan solution or recommendation on a going-forward basis.

To appreciate the potential impact of period-to-period deviations, consider for example two calling profiles arrays: one for the baseline data set that has been examined thus far, and another for a more variable data set. These two data sets, their average and standard deviations and the deviations of the usage profile of each period to the average, are shown in Table 9. TABLE 9 Comparison of Baseline and Variable Data Sets Training Set Test Set 1-5 1-5 1-6 1-6 Mon 1 Mon 2 Mon 3 Mon 4 Mon 5 Ave StdDev Mon 6 Ave StdDev Baseline 200 250 300 260 310 264 43.9 225 258 42.4 Calling Profile MOUs Ave. - X 64 14 36 4 46 33 >StdDev yes no no no yes no Second 350 400 375 600 325 410 109.8 320 395 104.9 Calling Profile MOUs Ave. - X 60 10 35 190 85 75 >StdDev no no no yes no no

Using one standard deviation unit (one sigma, or a) as the “filter” to identify and exclude discontinuities in a sequence of calling profiles, results in months 1 and 5 of the baseline sequence, and month 4 of the second calling profile sequence, being excluded from the analysis.

Another parameter that can be factored into the decision process of the present invention of what service plan to select for a given user or account, based upon an array of calling profiles and optimator 370 service plan instance 390 inputs, is the sensitivity of the result set to changes in calling profile. Specifically, the service plan solution set, plans A-E in the example used up to this point, should be tested by perturbing the usage profile in a positive and negative fashion by a fixed usage amount, for example, one σ. The results are shown in Table 10. TABLE 10 Results of Perturbing the Usage Profile by One Sigma Sum Mon 1-5 Training (using n = 0 Set Ave/ Mon 6 +1 Sigma −1 Sigma weighting) efficiency StdDev Mon 6 efficiency Cost eff. Cost eff. Calling 264/ 225 269 181 Profile 43.9 MOUs PLANS A $96 1.13 $50 1.38 $52 1.33 $50 1.38 B $103 1.06 $65 1.06 $65 1.06 $65 1.06 C $79 1.38* $42 1.64 $47 1.47* $37 1.86 D $97 1.13 $60 1.15 $60 1.15 $60 1.15 E $91 1.20 $37 1.86* $47 1.47* $27 2.56* Current $109 1.00 $69 1.00 $69** 1.00 $69** 1.00 Where * indicates the lowest cost plan option **this sensitivity cannot be performed unless the current plan is known

Based on the above “± one sigma” analysis, the optimal service plan option, minimizing the sensitivity of the decision to variations in usage both up and down, is plan E. Using only the upside variation results in the selection of plan C. Because there is less sensitivity to an upside in usage than a downside for many wireless service plans currently offered by the wireless service providers, either weighting the +1 analysis more heavily than the −1 analysis, or using only the +1 analysis results in the selection of plan C.

The implementation of the decision algorithms into the decidePlan process must allow for one of the following four (4) possible recommendations or actions:

-   -   1. The current plan is optimal; take no action.     -   2. There is a more optimal plan; if the savings is sufficient         (efficiency>1.x) where x is the historical percentage savings,         then change plans.     -   3. As a result of insufficient data, e.g., only one period of         usable data is available, there is a >±1 Sigma variation in the         most recent period's calling profile, etc.; therefore, take no         action, and flag the reason why no action was taken.     -   4. Even though an optimal plan was identified, other parameters         (e.g., a maximum period-to-period variance) were exceeded and         therefore an accurate recommendation cannot be possible.

As with the dataLoad 320, buildProfile 350 and optimator 370 processes, decidePlan 400 can be implemented as a manual or automated process. The following inputs may be used to launch the decidePlan process 400. Please note that blank spaces indicate input variable numbers that are considered to be within the scope of the present invention.

-   -   1. Client Name     -   2. Account: active accounts (default) or ______ account file     -   3. Analysis Parameters         -   a. Data window: available periods (default) or ______             periods         -   b. Calling profile selection filter: yes/no (default no)             within ______ Sigma         -   c. Sensitivity analysis range: ±______ % or ±______ Sigma         -   d. Minimum savings filter: ______ % (default 20%)

FIG. 12 shows the anticipated organization/sequence of steps of the decision process 900 that make up the decidePlan 400 process, which is described in detail herein below.

Presentation of Recommendations or Actions

If the MAMBA system 100 returns any recommendations for the given user, the MAMBA system 100 takes the user information and the information for the recommended cellular service plans and dynamically creates a report Web page that details this information. The HTML for this report Web page is stored in the database 74 for later display. Once the report Web page has been generated, the MAMBA system 100 sends an electronic mail message (email) to the specified user informing the user of the availability of more economical cellular service plans. This email may contain a hyperlink that will allow them to navigate to the stored HTML Web report. The HTML Web report page contains the information shown in Table 11. It should be noted that the presentation may also be made without use of the Web, but instead may be presented via any means of communication. TABLE 11 Information contained in HTML Web Report Client Name Date Generated Department ID User Name Current Plan Recommend Plan Name 1 (hyperlink) Name (hyperlink) Recommend Plan Name 2 (hyperlink) Recommend Plan Name 3 (hyperlink)

The user information is repeated for all requested users or accounts. The hyperlinks allow the viewer to view the specific information for the given plan.

The MAMBA system 100 causes the creation of a table that contains the HTML code for the report Web page and an ID value that will be part of the hyperlink that is sent to the user. The MAMBA system 100 may also cause the fields in Table 12 to be added to the USER table. TABLE 12 Fields the MAMBA System May Add to USER Table Field Name Data Type Length MAMBA Varchar 1 MAMBAMailDate DateTime MAMBAViewDate DateTime MAMBAReviewUser Varchar 50 MAMBAHTML Text 32765

The MAMBA field may contain either a “Y” or “ON” to denote to which user to send the MAMBA email for a given account. The MAMBAMailDate may contain the date the email was sent to the specified user, and the MAMBAReviewDate may contain the date the MAMBA report Web page was viewed. Further, the MAMBAReviewUser field may contain the user name of the person who viewed the MAMBA report Web page. Also, the MAMBAHTML field may contain the HTML code for the Web report page.

The MAMBA Component

The MAMBA Component (twiMAMBA) may be configured to implement a number of different methods, a few of which are shown by example in Tables 13-16 for completing the preferred functionality. These methods are as follows: TABLE 13 BuildProfile - Method that builds the calling_profile record A. Parameters: Name Type Description IclientID Integer client id to process DloadStartDate Date first date to process DloadEndDate Date last date to process IprofileIds( ) Integer array returned array of created profile ids InumZips Integer number of zip codes to process B. Returns True upon successful completion False upon failed completion

TABLE 14 RunProfiler - Method that launches the optimator process 370 A. Parameters: Name Type Description iProfileIDs( ) Integer array array of profile ids - returned by buildProfile dLoadStartDate Date returned array of evaluation ids B. Returns: True upon successful completion False upon failed completion

TABLE 15 AvgProfilesByClient - Method that takes a client name, a start and an end date, and then averages the usage totals for all profile records with a billing period between those dates and creates a new profile record. A. Parameters: Name Type Description SclientName string name of client to process DstartDate date first date to process DendDate date last date to process IavgProfileIDs( ) integer array array of average profile ids - returned by buildProfile B. Returns: True upon successful completion False upon failed completion

TABLE 16 AvgProfilesByAccount - Method that takes an account ID, a start and an end date, and then averages the usage totals for all profile records with a billing period between those dates and creates a new profile record. Name Type Description A. Parameters: IAccountId integer account id DStartDate date first date to process DEndDate date last date to process IAvgProfileIDs( ) integer array array of average profile ids - returned by buildProfile B. Returns: True - upon successful completion False - upon failed completion

FIG. 12 depicts the decision process 900 of the decidePlan process 400 (FIG. 5). The inputs of block 905, client_id, accounts, data_periods, cp_filter, sensitivity_range, and savings_hurdle, are directed to the select account info function of block 910. The select account info of 910 includes account_id, cp_ids, and service_plan_instances. Once the select account info 910 has been processed, the process proceeds to the decision block 915, where the decision is made if the cp count is less than 2. If “YES”, the process proceeds to block 920, for no action because of insufficient data or records. If the decision of block 915 is “NO”, the process proceeds to block 925 for the functions of determine cp data and set using cp_filter input. From block 925, the process moves to the decision block 930, where the decision is made if the cp count is less than 2. If “YES”, the process again moves to block 920 for no action because of unsufficient trend data. If the decision of block 930 is “NO”, the process proceeds to block 935 for the function of create candidate sp_id list based on most recent period. From the function of block 935, the process proceeds to block 940, for the function of compare candidate list to sp_ids for sp_instances in all applicable periods, based on cp list. From block 940, the process then proceeds to the decision block 950, where the decision is made, “are all sp_ids represented in all applicable periods?” If “NO”, the process proceeds to block 955, for the function of run optimator 370 to create additional sp_instances. From the function of 955, the process then proceeds to the function of block 960, perform historical prediction analysis and rank candidate sp_ids by efficiency factor. If the decision of block 950 is “YES” (all sp_ids are represented in applicable periods), then the process proceeds directly to the function of block 960 of performing historical prediction analysis. After the historical prediction analysis of block 960 is complete, the process proceeds to block 965 for performing sensitivity analysis, and rank candidate sp_ids by relative sensitivity. Once the function of block 965 is complete, the process then moves to the final step of 970, for recording decision results, mapping to the corresponding action and/or recommendation.

The Application Related to MAMBA System

The following represents a detailed description of the logic of the system and method for analyzing the wireless communication records and for determining optimal wireless communication service plans.

FIG. 14 depicts the operation 1000 of the buildProfile process 350. In block 1010, the process begins with the “Enter” function. In block 1020, a decision is made if getClientId is TRUE. If the answer is “NO”, the process then goes to the Exit function, shown in block 1220. If the answer is “YES”, then the process proceeds to block 1040. In block 1040, the decision is made if getCorpZip is TRUE. If not, the process proceeds to the Exit function 1220, if “YES”, the process proceeds to block 1060, where the decision is made if getNumbersByClient (rsNumbers) is TRUE and the Count is greater than zero. If the answer is “NO”, the process proceeds to the Exit function 1220. If “YES”, the process proceeds to block 1080, where the decision is made to Do while NOT reNumbers.EOF. If the answer is “NO”, the process goes to Exit function 1220. If “YES”, the process proceeds to block 1100, where the decision is made if getZipFromPhone is TRUE. If “NO” the process proceeds to Exit function 1220. If “YES”, the process proceeds to block 1120, where the decision is made if getCallDetailByNumber (rsCallDetail) is TRUE and the Count is greater than zero. If the answer is “NO”, the process proceeds to the Exit function 1220. If “YES”, the process proceeds to block 1140, where the decision is made to Do while NOT rsCallDetail.EOF. If the answer is “NO”, the process proceeds to the getZipCodes function of block 1280. If the answer is “YES”, the process proceeds to block 1160, where the decision is made if getType 1180, getWhen 1200, or getWhere 1221 are FALSE. If the answer is “NO”, the process moves to the “rsCallDetail.MoveNext” function of block 1260. If “YES”, the process moves to block 1240, where totalRejectedCalls is equal to total RejectedCalls+1. The process then proceeds to block 1260, where the function “rsCallDetail.MoveNext” is performed. Following this function, the system will again move to block 1140, Do while NOT rsCallDetail.EOF. This process is repeated until block 1140 is “NO”, and the process proceeds to the getZipCodes function of block 1280.

The getZipCodes process of block 1280, then proceeds to a decision in block 1300 if buildProfileDic is TRUE. If “NO”, the process goes to the Exit function of block 1220. If “YES”, the process proceeds to block 1320 where a decision is made if addProfileRecord is TRUE. If “NO”, the process proceeds to Exit function 1220. If “YES”, the process proceeds to block 1340, the “rsNumbers.MoveNext” function. From here, the process then returns to the decision block 1080 of do while NOT rsNumbers.EOF.

The getClientID process of block 1020 (FIG. 14) is depicted in FIG. 15. The process 1020 begins with block 1021, the Enter function, and continues to block 1022, the function of Select ID from client where name is equal to client name. The process ends in block 1023, the Exit function.

The getCorpZip process of block 1040 (FIG. 14) is depicted in FIG. 16. The process 1040 is entered in block 1041, and continues to block 1042, where the postal code is selected from the address. The process ends in block 1043, the Exit function.

The getNumbersByClient process of block 1060 (FIG. 14) is detailed in FIG. 17. The process begins with block 1061, the Enter function, and continues in block 1062, the function Select * from Telephone for client Id. The process ends in block 1063, the Exit function.

The getZipFromPhone process of block 1100 is detailed in FIG. 18. The process 1100 begins with block 1101, the Enter function, and continues to block 1102, the function call twi_getZipFromPhone stored procedure. The function ends in block 1103, the Exit function.

The getType process 1180 shown in block 1160 (FIG. 14) is detailed in the flowchart of FIG. 19. The process begins in block 1181, the Enter function, and continues in block 1182, where the decision is made if number_called is equal to ‘000’or ‘555 ’ or ‘411’ or len equals 3. If the answer of decision block 1182 is “YES”, the process moves to the Increment local call counter of block 1183, and then exits the process in block 1184. If the decision of block 1182 is “NO”, the process moves to the decision block 1185. In block 1185, the decision is made if getLataAndState for called_number and mobile_number is TRUE. If the answer is “NO”, the process moves to the Exit function block 1184. If “YES”, the process moves to the decision block 1189, where the decision is made if calledLATA is TollFree. If the answer is “YES”, the process proceeds to block 1183, for an Increment of local call counter. If the answer of decision block 1189 is “NO”, the process proceeds to the decision block 1190, where the decision If mobileLATA is equal to calledLATA. If the decision of block 1190 is “YES”, the process proceeds to the Increment local call counter block 1183, and then the Exit function of block 1184. If the decision of block 1190 is “NO”, the process proceeds to the decision block 1191, where the decision is made if mobileState is equal to the calledState. If the answer of decision block 1191 is “YES”, the process proceeds to block 1192 for the Increment Intrastate counter, and then to the Exit function of block 1184. If the decision of block 1191 is “NO”, the process proceeds to the Increment Interstate counter of block 1193, and then to the Exit function of block 1184.

The getLataAndState function of block 1185 (FIG. 19) is detailed in the flowchart of FIG. 20. In FIG. 20, the process begins in the Enter function in block 1186, and continues to block 1187, the function call twi_getLataAndState store procedure. Then, the process is exited in block 1188.

The getWhen function 1200 depicted in block 1160 (FIG. 14) is depicted in the flowchart of FIG. 21. The process is entered in block 1201, and proceeds to the decision block 1202, if dowId is Monday. If the answer is “YES”, the process proceeds to the decision block 1203, where the decision is made if the callTime is less than peak_start_time. If the answer of decision block 1203 is “YES”, the block 1204 Increment Weekend counter is signaled, followed by the Exit function 1205. If the answer is “NO” to decision block 1203, the process proceeds to the decision block 1206, where the decision is made if ElseIf callTime is less than peak_end_time. If the answer is “YES”, the process proceeds to block 1207 where the Increment Peak counter is signaled, and then the process proceeds to the Exit function 1205. If the decision is “SNO” in decision block 1206, the process proceeds to block 1208, for the Increment OffPeak counter, and then proceeds to the Exit function of block 1205. If the decision of block 1202 is “NO” (dowId does not equal Monday), then the process proceeds to decision block 1209, where the decision is made if dowId is equal to Tuesday-Thursday. If the answer is “YES”, the process proceeds to decision block 1210, where the decision is made if the callTime is less than the peak_start_time. If the answer to decision block 1210 is “YES”, the process proceeds to block 1210, the Increment OffPeak counter, and then to Exit function of block 1205. If the decision of block 1210 is “NO”, the process proceeds to block 1212, the increment peak counter, and then to the Exit function of block 1205. If the decision to block 1209 is “NO” (dowId is not equal to Tuesday-Thursday), then the process proceeds to decision block 1213, where the decision is made if the dowId is equal to Friday. If the decision is “YES”, the process proceeds to the decision block 1214, where the decision is made if callTime is less than peak_start_time. If “YES”, the callTime is less than the peak_start_time, then the process proceeds to block 1215, the increment offpeak counter, and then to the Exit function 1205. If the answer to decision block 1214 is “NO”, the process proceeds to decision block 1216, and the decision is made if ElseIf callTime is less than peak_end_time. If the answer is “YES”, the process proceeds to the increment peak counter of block 1217, and then to the Exit function of block 1205. If the decision of block 1216 is “NO”, the process proceeds to block 1218, the increment weekend counter, and then to the Exit function of block 1205. If the decision of block 1213 is “NO” (the dowId does not equal Friday), then the process proceeds to the decision block 1219, where the decision is made if Else dowId is equal to Saturday or Sunday. The decision of block 1219 is necessarily “YES”, wherein the process proceeds to block 1220, the Increment Weekend counter, and then to the Exit function 1205.

The getWhere process 1221 of block 1160 (FIG. 14) is depicted in the flowchart of FIG. 22. The getWhere process 1221 begins with the Enter function in block 1222, and proceeds to the decision block 1223, where the decision is made if number_called is equal to ‘000’. If “YES”, the process proceeds to block 1224, the Increment HomeZip counter, and then to the Exit function of block 1225. If the decision of block 1223 is “NO”, the process proceeds to the decision block 1226, where the decision is made if getZipFromCityState (originatingCityState) is TRUE. If the answer to decision block 1226 is “NO”, the process proceeds to the Exit function of block 1225. If the answer to decision block 1226 is “YES”, the process proceeds to decision block 1230, where the decision is made if retZip is equal to the homeZip. If “YES”, the process proceeds to block 1224, the Increment HomeZip counter, and then to the Exit function of block 1225. If the decision of block 1230 is “NO”, the process proceeds to the decision block 1231, where the decision is made if retZip is equal to corpZip. If the answer to the decision block 1231 is “YES”, the process proceeds to block 1232, the Increment CorpZip counter, and then to the Exit function of block 1225. If the decision of block 1231 is “NO”, the process proceeds to block 1233, the Add zip to zipCode dictionary, and then to the Exit function of block 1225.

The getZipFromCityState process referred to in block 1226 (FIG. 22) is detailed in the flowchart of FIG. 23. The process 1226 begins with the Enter function in block 1227, and then proceeds to the Call twi_getZipFromCityState stored procedure command of block 1228. The process then exits in block 1229.

The getZipCodes process of 1280 of FIG. 14 is detailed in the flowchart of FIG. 24. The getZipCodes process 1280 begins with the Enter function in block 1281, and proceeds to the decision block of 1282, where the decision is made if zipCode count is greater than zero. If “NO”, the process proceeds to the Exit function of bolck 1283. If the zipCode count is greater than zero (“YES”), the process proceeds to the decision block of 1284, wherein the decision is made If zipCode count is greater than or equal to max_us_zips. If “NO”, the process proceeds to block 1285, the looping operation through zipArray. The zipArray may contain any number of items according to several embodiments of the invention. By way of example, in one embodiment, the zipArray contains four items. The process may either then proceed to the decision block 1291, or continue on to block 1286, the looping operation through zipDictionary. From block 1286, the process can then either proceed to the decision block of 1287 or continue on to block 1290, the function Save max zip and count. At block 1290, the process then returns to the looping operation through zipDictionary of block 1286.

If the looping operation through zipDictionary of block 1286 proceeds through the decision block of 1287, the decision is made if the max zip and count is greater than the current zipArray item. If “NO”, the process returns to block 1285, the looping operation through zipArray. If the answer to decision block 1287 is “YES” (max zip and count are greater than current zipArray item), then the process proceeds to block 1288, where the max zip and count are added to zipArray. The process then proceeds to block 1289, to remove max zip and count from dictionary. From block 1289, the process then returns to block 1285, the looping operation through zipArray. Once the looping operation through zipArray of block 1285 is completed, the process proceeds to the decision block 1291, wherein the decision is made if zipDictionary count is greater than zero. If “NO”, the process then proceeds to the Exit function of block 1283. If “YES”, the process then proceeds to roll up remaining zip dictionary items in to the first Zip Array item as instructed in block 1292, and then proceeds to the Exit function of block 1283. Returning to the decision block of 1284, if “YES” (ZipCode count is greater than or equal to max_us_zips), then the process proceeds to the decision block 1293, wherein the decision is made if testLen is greater than zero. If “NO”, the process proceeds to the Exit function of block 1283. If “YES” (testLen is greater than zero), then the process proceeds to the function of block 1294, and looping operation through all zipCodes in zipDictionary.

The loop then proceeds to block 1295, where tempZip is equal to left(testLen) characters of zipCode. The process then proceeds to block 1296, where the function Add tempZip and count to tempZipDictionary is performed, and then returns to the looping operation through all zipCodes in zipDictionary of block 1294. If in block 1294 the testLen is equal to the testLen—1, the process proceeds to the Enter function of block 1281, and the getZipCodes begins again.

The buildProfilesDic process of block 1300 (FIG. 14) is detailed in the flowchart of FIG. 25. The process 1300 begins with the Enter function of block 1301, and proceeds to the decision block 1302, where the decision is made if total is less than any individual value. If “NO”, the process proceeds to the Exit function of block 1303. If “YES” (total is less than any individual value), then the process proceeds to the decision block 1304, where the decision is made if the total is greater than zero. If “NO”, the process proceeds to block 1306, for adding default values to profile dictionary, and then to the Exit function of block 1303. If the decision of block 1304 is “YES” (total is greater than zero), then the process proceeds to block 1305, for adding actual values to profile dictionary, and then to the Exit function of block 1303.

The addProfileRecord process of block 1320 (FIG. 14) is detailed in the flowchart of FIG. 26. The process 1320 begins with the Enter function of block 1321. The process then proceeds to block 1323 for inserting into the calling_profile. The process then ends with the Exit function 1324.

Once the profiles are built, according to the steps detailed in the flowchart of FIGS. 14-26, the profiles are then run, as detailed in the flowchart of FIG. 27. The runProfiler process 1400 begins with the Enter function of block 1401, and proceeds to the function of block 1402, of Set oProfiler=CreateObject(“TWIOptimizer.Optimator”). The process then proceeds to block 1403, For iCount=0 to Ubound(iProfileIds). From block 1403, the process may proceed to block 1404, Set oProfiler=Nothing, and then to the Exit function of block 1405. Block 1403 may also proceed to the decision block of 1406, where the decision is made If oProfiler.DoEval is TRUE. If “NO”, the process then proceeds to the Exit function of block 1405. If “YES” (oProfiler.DoEval is TRUE), then the process returns to block 1403, For iCount=0 to Ubound(iProfileIds).

The doEval process of block 1406 (FIG. 27) is detailed in the flowchart of FIG. 28. The doEval process 1406 begins with the Enter function of block 1410, and proceeds to the decision block 1420, where the decision is made If getUserProfile is NOT nothing. If “NO”, the process proceeds to the Exit function of block 1440. If “YES” (getUserPrfile is NOT nothing), then the process proceeds to the decision block 1460, where the decision is made If findPackages is True. If “NO”, the process proceeds to the Exit function of block 1440. If “YES” (find Packages is True), then the process proceeds to the decision block of 1490. In the decision block of 1490, the decision is made If calcCosts is True. If “NO”, the process proceeds to the Exit function of block 1440. If “YES”, the process then proceeds to block 1600 for createEvaluation, and then to the Exit function 1440.

The getUserProfile process of block 1420 (FIG. 28) is described in greater detail in the flowchart of FIG. 29. The getUserProfile process 1420 begins with the Enter function of block 1425, proceeds to block 1430 for Clear out m_dicProfile. The process then proceeds to block 1435 for getProfile, and then to the Exit function 1440.

The getProfile process of block 1435 (FIG. 29) is described in greater detail in the flowchart of FIG. 30. The getProfile process 1435 begins with the Enter function of block 1436, and proceeds to block 1437 for Select from calling_profile. The process then proceeds to the Exit function of block 1438.

The findPackages process of block 1460 (FIG. 28) is described in greater detail in the flowchart of FIG. 31. The findPackages process 1460 begins with the Enter function of block 1461, and then proceeds to the decision block of 1462, where the decision is made if profile is found. If “NO”, the process proceeds to the Exit function of block 1463. If “YES” (profile is found), the process proceeds to block 1463 for Get home zip, and then to block 1464, twiOptimizer.SPPackage.getPackagesByZIP, where packages are added to allPackages dictionary 1465. The process proceeds to block 1466 where it performs the Get corp zip function, and then proceeds to the decision block of 1467, where the decision is made if corp zip is found and corp zip is greater than or less than the home zip. If the decision of block 1467 is “NO”, the process proceeds to block 1468 for removing all items from m_dicBasePackages. The process then proceeds to block 1469 for performing the function Add all base packages form allPackages dictionary to m_dicBasePackages. The process then proceeds to block 1470 where it performs the function Add all non-base packages from allPackages dictionary to m_dicBasePackages, and then proceeds to the Exit function 1463. If the decision of block 1467 is “YES” (corp zip is found and corp zip is greater than or less than home zip), the process proceeds to block 1464, where it performs the function twioptimizer.SPPackage.getPackagesByZip. The process then proceeds to block 1465 where it performs the function Add packages to allPackages dictionary. From block 1465, the process continues on to block 1468, where it performs the function Remove all items from m_dicBasePackages, and the process continues on until the Exit function of block 1463.

The getPackagesByZIP process of block 1464 (FIG. 31) is described in greater detail in the flowchart of FIG. 32. The getPackagesByZIP process 1464 begins with the Enter function 1471, and proceeds to the decision block 1472, where the decision is made if carriers count is equal to zero. If “NO”, the process proceeds to block 1474, where rs equals getPackagesByZipAndCarrier, and then to the decision block 1475. If the answer to the decision block 1472 is “YES” (carriers count is equal to zero), then the process proceeds to block 1474, where rs equals getPackagesByZip. From block 1473, the process then proceeds to the decision block 1475, where the decision is made if rs is NOT nothing and rs.EOF is FALSE. If the answer is “NO”, the process proceeds to the Exit function of block 1476. If the answer to the decision block 1475 is “YES” (rs is NOT nothing and rs.EOF is FALSE), then the process proceeds to block 1477, While NOT rs.EOF.

From block 1477, the process may then proceed to the Exit function of block 1476, or it may proceed to block 1478, where it performs the function Save rs values to newPackage. From block 1478, the process proceeds to the decision block 1479, where the decision is made if package type equals base or extendedLocalCalling. If “NO”, the process proceeds to the decision block of 1482. If “YES” (package type is equal to base or extendedLocalCalling), the process then proceeds to the decision block 1480. In the decision block 1480, the decision is made areZips in package coverage area. If “NO”, the process then proceeds to the decision block 1482. If “YES” (areZips in package coverage area), then the process proceeds to block 1481, where it performs the function Add minutes to newPackage coveredZips.

From block 1481, the process then proceeds to the decision block 1482, where the decision is made is package type equal to Base. The answer to the decision block 1482 is necessarily “YES”, and the process proceeds to block 1483, where it performs the function Add minutes for Digital and Analog Roaming. From block 1483, the process proceeds to block 1484, where it performs the function Save profile zip for package.

From block 1484, the process proceeds to block 1485, where it performs the function Add package to retDic. From block 1485, the process returns again to block 1477, and this loop is repeated until the function is rs.EOF. Then the process proceeds from block 1477 to the Exit function of block 1476.

The selectCoveredZIPs process of block 1480 (FIG. 32) is described in greater detail in the flowchart of FIG. 33. The selectCoveredZIPs function 1480 begins with the Enter function of block 1486, and then proceeds to block 1487, where it performs the function Call areaZIPsInPackageCoverageArea. Upon completion of the function of block 1487, the process proceeds to the Exit function of block 1488.

The calcCosts process of block 1490 (FIG. 28) is described in greater detail in the flowcharts of FIG. 34A and FIG. 34B. The process calcCosts 1490 begins with the Enter function of block 1491, and proceeds to the decision block 1492, where the decision is made if profile is found. If “NO”, the process proceeds to the Exit function of block 1493. If “YES” (Profile is Found), the process proceeds to the function of block 1494, For each base package, and then proceeds to the function of block 1495, twiOptimizer.SPPackage.calcCost. From block 1495, the process proceeds to a looping operation beginning with block 1496, for each optional package.

From block 1496, the process can either proceed directly to the Calculate minimum costs function of block 1506, or the function of block 1495, twiOptimizer.SPPackage.calcCost. From block 1495, the process proceeds to the decision block 1497, where the decision is made whether package type equals longdistance. If “YES” (package type is longdistance), the process proceeds to the decision block 1498, where the decision is made if current savings is greater than max savings. If the answer to the decision block 1498 is “NO” (current savings is not greater than max savings), the process proceeds to the decision block 1500. If “YES” (current savings is greater than max savings), the process proceeds to the function of block 1499, Save current savings.

From block 1499, the process then proceeds to the decision block 1500. In the decision block 1500, the decision is made if package type is equal to offpeak, weekend, or offpeakweekend. If “YES” (package type is either offpeak, weekend, or offpeakweekend), the process proceeds to the decision block 1501. In the decision block 1501, the decision is made whether current savings are greater than max savings. If “NO”, the process proceeds to the decision block 1503. If “YES” (current savings are greater than max savings), the process proceeds to the function of block 1502, Save current savings.

From block 1502, the package type then proceeds to the decision block 1503. If the decision of block 1500 is “NO” (package type is not offpeak, weekend, or offpeakweekend), then the process proceeds to the decision block 1503, where the decision is made if package type is equal to extendedLocalCalling. If “NO”, the process returns back to the function of block 1406, for each optional package, and then proceeds to the function of block 1495, twiOptimizer.SPPackage.calcCost, and the procedure is run again. If the decision of block 1503 is “YES” (package type is extendedLocalCalling), the process then proceeds to the decision block 1504. In the decision block 1504, the decision is made whether current savings is greater than max savings. If the answer to the decision of block 1504 is “NO”, the process returns again to the looping operation of block 1496, and the procedure is run again for each optional package. If the answer to block 1504 is “YES” (current savings is greater than max savings), then the process proceeds to the function of block 1505, Save current savings.

From block 1505, the process then returns to block 1496, where the procedure is repeated. Once the procedures have been calculated for each optional package of block 1496, the process then continues on to the function of block 1506, Calculate minimum costs. From block 1506, the process then proceeds to the function of block 1507, Add costs to m_dicBasePackages. From block 1507, the process proceeds to the function of block 1508, Use twioptimizer.ServicePlan.GetServicePlansById to Get activation fee and add it to m_dicBasePackages.

From block 1508, the process continues to the function of block 1509, Build array of lowest cost package ids. The array may contain any number of items according to several embodiments of the invention. By way of example, in one embodiment of the invention, the array contains three items. From block 1509, the process continues to the function of block 1510, a looping operation through array of lowest cost package ids and set the matching packages includedInEval flag to true. From block 1510, the process then proceeds to the Exit function of block 1493.

The process for the calcCost function of block 1495 (FIG. 34) is detailed in the flowchart of FIGS. 35A and 35B. The process 1495 begins with the Enter function of block 1511, and proceeds to the decision block of 1512, where the decision is made if package type is equal to base. If “YES” (package is base), then the process proceeds to the function of block 1513, Calculate peak over minutes. The process then proceeds to the function of block 1514, Calculate off-peak over minutes, followed by the function of block 1515, Calculate long distance (LD) minutes.

The process then proceeds to the function of block 1516, Calculate roaming minutes, and then to block 1517, Get the total roaming minutes for those profile ZIPS not in the current calling area. From block 1517, the process proceeds to block 1518, the function Now Calculate the corresponding costs, and then proceeds to the decision block 1519, where the decision is made if package type is longdistance. Further, if the decision of block 1512 is “NO” (package type is not base), the process proceeds to the decision block of 1519. If the decision of block 1519 is “NO”, the process then proceeds to the decision of block 1523, as to whether Package type is equal to offpeak. If the decision of block 1519 is “YES” (package type is equal to longdistance), the process proceeds to the function of block 1520, Calculate the number of minutes over the plan minutes.

From block 1520, the system proceeds to block 1521, the function Find how much this package saves against the current base package cost. Once the function of 1521 is complete, the process moves to the function 1522, Now calculate the corresponding costs. Once the function of block 1522 is completed, the process then moves to the decision block 1523, where the decision is made if package type is equal to offpeak. If the decision is “NO”, the process proceeds to the decision block of 1526. If the decision of block 1523 is “YES” (package type is offpeak), then the process proceeds to the function of block 1524, Calculate the offpeak minutes cost.

After the function of block 1524, the process proceeds to the function of block 1525, Find how much this package saves against the current base package cost. Upon completion of the function 1525, the process then proceeds to the decision block of 1526, where the decision is made if package type is equal to weekend. If “NO”, the process proceeds to the decision block 1529. If the decision of block 1526 is “YES” (package type is weekend), then the process proceeds to the function of block 1527, Calculate the weekend minutes cost. Upon the completion of the function of block 1527, the process proceeds to the function of block 1528, Find how much this package saves against the current base package cost. Upon completion of the function of block 1528, the process will then proceed to the decision block 1529, where the decision is made if package type is equal to offpeak weekend. If “NO”, the process proceeds to the decision block 1532. If the decision of block 1529 is “YES” (package type is offpeak weekend), then the process proceeds to the function of block 1530, Calculate the offpeak minutes cost.

Upon completion of the function of block 1530, the process continues to the function of block 1531, Find how much this package saves against the current base package cost. Upon completion of this function, the process then proceeds to the decision block 1532, where the decision is made if package type is equal to extended local calling. If “NO”, the process then proceeds to the Exit function of block 1535. If the decision of block 1532 is “YES” (package is extended local calling), then the process proceeds to the function of block 1533, Calculate the extended local calling minutes cost. After the function of block 1533, the process continues to the function of block 1534, Find how much this package saves against the current base package cost. The process then proceeds to the Exit function 1535.

The getServicePlanByID process of block 1508 (FIG. 34) is detailed in the flowchart of FIG. 36. The getServicePlanByID process 1508 begins with the Enter function of block 1535, and proceeds to the function of block 1536, rs equals getServicePlanByID. The process then proceeds to the decision block 1537, where the decision is made if NOT rs is nothing and NOT rs.EOF. If “NO”, the process proceeds to the Exit function of block 1538. If “YES” (NOT rs is nothing and NOT rs.EOF), then the process continues to the function of block 1539, Save rs to serviceplan object. From block 1539, the process then proceeds to the Exit function of block 1538.

The createEvaluation function of block 1600 (FIG. 28) is detailed in the flowchart of FIG. 37. The process createEvaluation 1600 begins with the Enter function of block 1601, proceeds to the function of block 1620, putEvaluation, and then finishes with the Exit function of block 1640.

The putEvaluation process of block 1620 (FIG. 37) is detailed in the flowchart of FIG. 38. The process putEvalution 1620 begins with the Enter function 1621, proceeds to the function of block 1622, Insert in to rate plan evaluation, and then proceeds to the function of block 1623, a looping operation through base packages. The process then proceeds to the decision block 1624, where the decision is made if includedInEval is TRUE. If “NO”, the process then proceeds to the next base package, as depicted in block 1625.

From block 1625, the process then returns to the looping operation base packages of block 1623. If the decision of block 1624 is “YES” (includedInEval is TRUE), then the process proceeds to the function of block 1627, Insert in to service plan instance. The process then proceeds to the function of block 1628, Insert in to SPI_RPE_LINK, before proceeding to the function of block 1629, Insert in to package instance. The process then continues to the function of block 1630, the looping operation through optional packages. In the looping operation, the process proceeds to the decision block 1631, where the decision is made if package selected is True. If “NO”, the looping operation then goes directly to the next optional package, as shown in block 1633, before returning through to the looping operation through optional packages of block 1630. If the decision of block 1631 is “YES” (if package selected is True), then the process proceeds to the function of block 1632, Insert in to package instance, and then to the function of block 1633 for the next optional package.

Once the looping operation is completed, the process then proceeds from block 1633 to the function of block 1625 for the next base package, which is part of the looping operation through based packages as depicted in block 1623. Once the looping operation through base packages is complete, the process then moves from block 1625 to the Exit function of block 1626.

The calling profiles may be averaged by client or account. The avgProvilesByClient process 1700 is depicted in the flowchart of FIG. 39. The avgProfilesByClient process 1700 begins with the Enter function of block 1701, and proceeds to the decision block 1702, where the decision is made if getClientId is TRUE. If “NO”, the process then proceeds to the Exit function of block 1703. If “YES” (getclientId is TRUE), then the process proceeds to the decision block 1704. In block 1704, the decision is made If getNumbersByClient (rsNumbers) is TRUE and count is greater than zero. If “NO”, the process proceeds to the Exit function of block 1703. If “YES” (getNumbersByClient (rsNumbers) is TRUE and count is greater than zero), the process proceeds to the decision block 1705, where the decision is made Do While NOT rsNumbers.EOF. If “NO”, the process proceeds to the Exit function of block 1703. If “YES” (NOT rsNumbers.EOF), then the process proceeds to the decision block 1706.

The decision is made in block 1706 if avgProfilesByAccount is TRUE. If “NO”, the process proceeds to the Exit function of block 1703. If “YES” (avgProfilesByAccount is TRUE), the process proceeds to the function of block 1707, rsNumbers.MoveNext. From the function of block 1707, the process then returns to the decision block 1705, and is repeated while NOT rsNumbers.EOF. The getclientId function of block 1702 has been previously described and is depicted in process 1020 (FIG. 15). The getNumbersByclient function of block 1704 has been previously described and is depicted in the flowchart of process 1060 (FIG. 17).

The avgProfilesByAccount process 1706 (FIG. 39), is depicted in the flowchart of FIG. 40. The avgProfilesByAccount process 1706 begins with the Enter function shown in block 1750. The process then proceeds to the decision block 1760, where the decision is made if getProfileRecords (rsProfiles) is TRUE and the count is greater than zero. If “NO”, the process proceeds to the Exit function of block 1770. If “YES” (getProfileRecords is TRUE and count is greater than zero), then the process proceeds to the decision block 1780, a Do while NOT rsProfiles.EOF function. If “NO”, the process proceeds to the getZipCodes function of block 1820. If “YES” (NOT rsProfiles.EOF), then the process proceeds to the decision block 1790. In the decision block 1790, the decision is made if homeZip is the same. If “NO”, the process proceeds to the getZipCodes function of block 1820. If “YES” (homeZip is the same), then the process proceeds to the function of block 1800, Sum all call values.

From block 1800, the process then continues to the function of block 1810, iPeriods equals iPeriods plus 1. The process then returns to the function Do while NOT rsProfiles.EOF of block 1780. Once the block 1780 is “NO”, and leads to the getZipCodes function of block 1820, the process then continues to the decision block 1830. The decision is made in block 1830 if iPeriods is greater than zero. If “NO”, the process proceeds to the Exit function of block 1770. If “YES” (iPeriods is greater than zero), then the process continues to the function of block 1840, Average all sums. The process then continues to the Build profile dictionary function of block 1300. The Build profile dictionary function is depicted in process 1300 (FIG. 25). The process then continues to the addProfileRecord of block 1320 (FIG. 26), before proceeding to the Exit function of block 1770.

The getProfileRecords process of block 1760 is depicted in greater detail in the flowchart of FIG. 41. The getProfileRecords process 1760 begins with the Enter function 1761, proceeds to the Call twi_getProfileRecords stored procedure of block 1762, and then finishes with the Exit function of block 1763.

Pooling Process

A telecommunication carrier may offer an arrangement where two or more related users, each under an individual rate plan from the telecommunication carrier, can re-allocate the total amount of time that the users used during a month. Under this arrangement, the usage time can be re-allocated to any of the plans in a manner that optimizes the costs. For example, if a first user is on a 300-minute plan and uses 500 minutes, and a second user is on a 1000-minute plan but only uses 800 minutes, then the two users can divide the total 1300 minutes of service usage between the two plans. In this case, 200 minutes of usage time can be transferred from the first plan to the second plan so that the allotted usage time for the first user is not exceeded. Since the carriers will typically charge a much higher rate after the allotted minutes are used, the process of sharing usage time between two users minimizes the incurred extra charge for usage time beyond the allotted time. In this example, the first user does not incur any extra charge for the 200 minutes beyond the allotted time.

According to an improved pooling process as disclosed herein, two or more related users can be grouped together to better optimize telecommunication costs. The related users may be co-workers in a business or members of a family, for example. In this regard, multiple users may be included in the pooling process and groups of the users can be created such that each group is optimized to a particular rate plan. For example, consider a case where there are seven users and five available rate plans from a particular carrier. With the five rate plans, there may be up to five groups or pools. For the sake of simplicity, consider the case where two groups are created in which the seven users are pooled.

To pool the seven users into two groups, the following process may be initiated. First, from the users' call detail records, a calling profile record is generated for each user. The calling profile record may contain a usage parameter, such as the average number of minutes used per month. In this example, the average monthly usage time is evaluated. The users are arranged or ranked in an order from the lowest time user to the highest time user, or vice versa, and then pooled into groups with other users having similar calling patterns. Also, the groups can be recombined or re-pooled into a number of different combinations.

One scheme, among others, for pooling users includes the following: With the users arranged in an order or rank based on telecommunication service time usage, a first combination is considered in which one user at one end of the range of ranks is put in a group alone and the remaining users are grouped together. In the above example, a low service time user (or high service time user) is placed in one group and the other six users are placed in another group. The optimal rate plan for the group consisting of only one user is evaluated by applying the monthly usage time for the user to the available rate plans and determining the most cost-effective rate plan. For the other group of the remaining six users, the total time for the six users is summed and the average is calculated. From this average, an optimal rate plan can be selected and the usage time for the users in the group can be re-distributed such that each user is charged for the average usage time. The total cost can be calculated by applying the average time usage to the selected rate plan for each user and summing the totals. Thus, the optimal rate plans for the two groups are determined by considering the average usage time within each group.

At this point, the pooling combination can be changed and the above steps repeated for all reasonable combinations with two groups. The groupings may be changed by including the two lowest (or highest) time users in one group and the remaining five users in another group. The same calculations are made to determine the best plans for each group and the total costs are calculated. This regrouping, or re-pooling, is performed for all six combinations of groups in which there are seven users and two groups and the groups are divided within a range of rankings based on a usage parameter. This process is repeated until the best combination is determined.

The MAMBA system 100 of FIG. 1 may be configured to include a processor that is capable of performing a pooling process. For example, processor 71 of FIG. 2A may include MAMBA software 10 that pools a plurality of users into at least two groups and determines cost-effective pooling combinations and corresponding rate plans for these combinations for reducing the telecommunication service costs.

FIG. 42 is a flow chart of an embodiment of a pooling process that pools a plurality of users into only two groups or pools. In this embodiment, the pooling process may be performed by the MAMBA software 10 or other suitable program or executable system. The pooling process includes ranking the telecommunication users in an order based on a usage parameter, as indicated in block 1850. The usage parameter may be any applicable parameter of the calling profile record, as described above with respect to FIGS. 3, 5, 8, etc. For example, in the preferred embodiment, the usage parameter is the average number of minutes per billing period that a particular user uses the telecommunication service. The billing period is typically one month. Block 1850 may include additional processes that are described below with respect to FIG. 44.

The pooling process of FIG. 42 further includes pooling the plurality of telecommunication users into two groups, as indicated in block 1852. The users are pooled according to the ranking made in block 1850 such that each group includes users having a usage parameter within a certain range. For example, with seven users, three users having a range of service time usage between 0 and 500 minutes per month may be in a first group and the remaining four users having a range of service time usage between 501 and 1800 minutes may be in a second group. The initial pooling of users may include placing one user at one extreme in the ranking order in one group and placing the remaining users in another group.

After initially pooling the users, the process includes block 1854 in which the total estimated cost is calculated with respect to the most cost-effective rate plans in connection with the pooled groups. Calculating the total estimated cost may include the process described with respect to the description of FIG. 45 below. In decision block 1856, it is determined whether or not any more re-pooling combinations are possible. If so, the process returns to block 1854 until all possible pooling combinations have been arranged and the total estimated costs for each combination is calculated. If there are no more combination in block 1856, flow continues to block 1858, where the most cost-effective pooling combination and corresponding rate plans are determined. This may be accomplished by merely recording the total estimated costs from block 1854 and determining the pooling combinations and rate plans with the lowest estimates.

FIG. 43 is a flow chart illustrating another embodiment of a pooling process for pooling telecommunication users. In this embodiment, as opposed to the embodiment of FIG. 42, more than two groups or pools may be created in which users may be placed. In this regard, more grouping or pooling combinations may be attempted to better analyze an optimal arrangement for reducing telecommunication costs.

In block 1860, the users are ranked based on a usage parameter, as defined in more detail with respect to FIG. 44. In block 1862, two groups are created in which users may be placed. In block 1864, the users are pooled into the two groups. In a later step after one or more groups are added, the users are pooled into the respective number of groups, noting that each group contains at least one user. In block 1866, the total estimated cost is calculated, as described below with respect to FIG. 45.

If it is determined in decision block 1868 that more re-pooling combinations are possible with the respective number of groups, then flow proceeds back to block 1866. Otherwise, the process continues to block 1870. It should be emphasized that the number of pooling combinations will be different depending on the number of groups in which users are pooled. Therefore, the looping of block 1868 will be more frequent when the number of groups approaches one half of the number of users plus one.

In decision block 1870, it is determined whether or not the number of groups is equal to the number of rate plans available. If not, then the process goes to block 1872 where another group is added and then flow returns to block 1864 to repeat the pooling and re-pooling with a greater number of groups. If the numbers are equal in block 1870, flow continues to block 1874 where the most cost-effective pooling combination and corresponding rate plans are determined.

FIG. 44 is a flow chart of an embodiment of a sub-routine for ranking users based on a usage parameter. This sub-routine may be performed in place of the above-described blocks 1850 and/or 1860. The user-ranking process includes receiving call detail records for each user, as indicated in block 1880. From the call detail records, calling profile records for each user are calculated, as indicated in block 1882. Then, according to block 1884, the usage parameter, such as the average number of minutes of telecommunication service used by each user during one billing period, is determined. In block 1886, the users are ranked based on the usage parameter, e.g. average number of minutes per billing period. In this embodiment, one billing period may be equal to one month.

FIG. 45 is a flow chart of an embodiment of a cost-calculating sub-routine for calculating the total estimated cost of a plurality of users grouped or pooled as mentioned above. This or other embodiments may be performed as a sub-routine of the process described with respect to blocks 1854 and 1866. In block 1890, the usage parameter for the users within each group is averaged. For example, if the usage parameter of interest is the telecommunication service usage, then the average may be an average of the minutes of telecommunication service usage per billing period. Other examples of the usage parameter may include the distribution according to the time-of-day and day-of-week in which the calls were made, the distribution according to whether the calls were local or toll, and the distribution according to the location where the calls were made or received.

In block 1892, a cost-effective rate plan is selected from a number of available rate plans, typically offered by a single carrier. The selected rate plan is selected based on the usage parameter average for each group. Typically, a rate plan offering a certain amount of monthly time closest to the average from block 1890 will be selected. However, based on other factors, such as an overage charge incurred when usage exceeds the allotted monthly time, the best rate plan may be one that offers a monthly time greater than the service usage average.

In block 1894, the usage parameter average calculated in block 1890 is applied to the rate plan selected in block 1892 for each group to run a cost evaluation process for each user or group. In block 1896, the total estimated cost is calculated by adding the cost of all the telecommunication users on their respective group rate plan at the averaged monthly time.

It should be emphasized that the above-described embodiments of the present invention, particularly, any “preferred” embodiments, are merely possible examples of implementations, merely set forth for a clear understanding of the principles of the invention. Many variations and modifications may be made to the above-described embodiment(s) of the invention without departing substantially from the spirit and principles of the invention. All such modifications and variations are intended to be included herein within the scope of this disclosure and the present invention and protected by the following claims.

A method for pooling telecommunication users to reduce telecommunication service costs, the method comprising: ranking a plurality of telecommunication users in an order based on service time usage per month; pooling the telecommunication users into first and second groups such that the first group includes the highest ranked telecommunication user and the second group includes the remaining telecommunication users; averaging the service time usage for the telecommunication users in each group to obtain a service time usage average for each group; selecting, for each group, a cost-effective rate plan from a number of available rate plans, the cost-effective rate plan selected on the basis of the service time usage average; applying the service time usage average to the selected rate plan for each telecommunication user in the respective group to obtain an estimated cost for each telecommunication user; mathematically combining the estimated costs for each telecommunication user to obtain a total estimated cost; moving the highest ranked telecommunication user in the second group to the first group; repeating the averaging, selecting, applying, combining, and moving until only one telecommunication user remains in the second group; and determining one or more of the most cost-effective pooling combinations and corresponding rate plans based on the respective total estimated costs.
 2. The method of claim 1, wherein pooling the telecommunication users further comprises pooling the telecommunication users into three or more groups.
 3. The method of claim 1, wherein pooling the telecommunication users further comprises pooling the telecommunication users into a number of groups not more than the number of available rate plans.
 4. A method for pooling telecommunication users into groups, the method comprising: ranking a plurality of telecommunication users in an order based on a usage parameter; and pooling telecommunication users into at least two groups, wherein each group comprises at least one telecommunication user within a range of ranks based on the usage parameter.
 5. The method of claim 4, further comprising calculating a total estimated cost for the telecommunication users within each group to use a cost-effective rate plan selected from a group of available rate plans.
 6. The method of claim 5, wherein calculating the total estimated cost further comprises: averaging the usage parameter for the telecommunication users within each group; selecting a cost-effective rate plan from a plurality of available rate plans based on the usage parameter averages for each group; applying the respective usage parameter averages to the respective selected rate plans for each user within each group; and calculating a total estimated cost for the plurality of telecommunication users.
 7. The method of claim 5, further comprising: re-pooling the telecommunication users into other possible pooling combinations and calculating the respective total estimated costs for the telecommunication users within each re-pooled group to use a cost-effective rate plan; and determining the most cost-effective pooling combination and respective rate plans.
 8. The method of claim 7, wherein re-pooling further comprises re-pooling the telecommunication users into a same number of groups, whereby each re-pooled group comprises at least one telecommunication user and further comprises a different range of ranks.
 9. The method of claim 8, further comprising: averaging the usage parameter for the telecommunication users within each re-pooled group; selecting a cost-effective rate plan from the plurality of available rate plans based on the usage parameter averages for each re-pooled group; and calculating an estimated cost for the plurality of telecommunication users based on the respective usage parameter averages for the respective re-pooled group.
 10. The method of claim 9, further comprising: repeating the re-pooling, averaging, selecting, and calculating for each possible range of ranks; and determining the most cost-effective pooling combination and respective rate plans based on the estimated costs.
 11. The method of claim 4, wherein ranking further comprises: receiving a plurality of call detail records representing telecommunication service usage by the plurality of telecommunication users during a predetermined period; calculating a calling profile record for each telecommunication user based on the call detail records; and determining the usage parameter from the calling profile records.
 12. The method of claim 4, wherein the usage parameter is the average number of minutes of telecommunication service used by a telecommunication user during one billing period.
 13. The method of claim 4, wherein the usage parameter is a parameter related to wireless telecommunication service.
 14. A system comprising: means for ranking a plurality of telecommunication users in an order based on a telecommunication service usage parameter; and means for pooling the telecommunication users into a plurality of groups, each group comprising at least one telecommunication user having a rank based on the telecommunication service usage parameter within a defined range.
 15. The system of claim 14, further comprising: means for re-pooling the telecommunication users to determine the most cost-effective pooling combination with respect to a plurality of available rate plans.
 16. A computer program stored on a computer readable medium, the computer program comprising: logic configured to pool a plurality of telecommunication users into at least two groups, each group comprising at least one telecommunication user having a usage parameter within a defined range; and logic configured to determine the most cost-effective rate plans based on the pooling of telecommunication users.
 17. The computer program of claim 16, wherein the logic configured to pool is further configured to optimize a pooling combination with respect to a plurality of available rate plans for reducing telecommunication service costs.
 18. The computer program of claim 16, wherein the logic configured to determine further comprises: logic configured to average the usage parameter for the telecommunication users in each group to obtain a usage parameter average for each group; logic configured to select a cost-effective rate plan for each group on the basis of the usage parameter average; logic configured to apply the usage parameter average to the selected rate plan for each telecommunication user in each respective group; and logic configured to calculate a total estimated cost for the plurality of telecommunication users.
 19. The computer program of claim 18, further comprising logic configured to re-pool the telecommunication users to obtain the pooling combination with a relatively low total estimated cost.
 20. The computer program of claim 16, wherein the usage parameter is defined as the service time usage per billing period.
